We report herein the design and synthesis of novel 1-[3-(dimethylamino)propyl]indolin-2-one derivatives based on the structural features of Sunitinib, a known multitargeted receptor tyrosine kinase inhibitor, and TMP-20, a previously discovered compound with good antitumor activity in our lab. These newly synthesized derivatives were evaluated for in vitro activity against five human cancer cell lines
我们在此报告基于已知的多靶点受体酪氨酸激酶抑制剂舒尼替尼和先前发现的化合物TMP-20的结构特征,设计和合成新型1- [3-(二甲基氨基)丙基]吲哚-2-酮衍生物在我们的实验室中具有良好的抗肿瘤活性。评价了这些新合成的衍生物对五种人类癌细胞系和VEGF / bFGF刺激的HUVEC的体外活性。结果显示,所有目标化合物1a – p均显示出强大的抗肿瘤活性,化合物1e – h(IC 50值:0.45–5.08μM)比舒尼替尼(IC 50值:1.35–6.61μM)更具活性,并且活性最高的化合物1h(IC50:0.47–3.11μM)对所有五种癌细胞系的效力比舒尼替尼高2.1–4.6倍。另外,与舒尼替尼一样,1a – p对bFGF刺激的HUVEC以外的VEGF刺激的HUVEC具有更高的选择性。
